Housing for tape cartridge and hold for mold for forming the same

Abstract

In a housing for tape cartridge which holds therein a tape reel on which a medium in the form of a tape is wound, an outer surface portion of a side wall, out of surrounding walls, of the housing facing the direction of cartridge insertion into a recording-reproducing apparatus has a draft of zero degree where it comes in contact with positioning means of the apparatus. In a mold for forming the housing, a mold portion that forms an outer surface portion of a side wall, out of surrounding walls, of the housing facing the direction of cartridge insertion into a recording-reproducing apparatus, is constituted by a slide having a plane perpendicular to the direction of insertion.

What is claimed is:  
     
       1. The housing for a tape cartridge, comprising: 
       surrounding walls formed of molded plastic material holding therein a tape reel on which a tape medium is wound, wherein an outer surface portion of a side wall, out of the surrounding walls of the housing, facing a direction of cartridge insertion into a recording reproducing apparatus has a draft of zero degrees, wherein said outer surface portion is adapted to come into contact with positioning means of the apparatus, and wherein said outer surface portion having said draft of zero degrees is formed by a slide mold portion having a
